The IM LS6 II 1.5T 66 kWh (313 Hp) Extended Range, launched in September 2025, marks IM’s entry into the competitive plug-in hybrid electric vehicle (PHEV) SUV market. Positioned as a mid-range offering within the LS6 II lineup, this variant strikes a balance between electric driving range and the convenience of a gasoline engine. It’s targeted towards consumers desiring a premium SUV experience with reduced emissions and improved fuel efficiency. The LS6 II is built upon a dedicated electric vehicle architecture, demonstrating IM’s commitment to new energy vehicles.
Powertrain & Engine Architecture
The IM LS6 II 1.5T utilizes a sophisticated PHEV powertrain. At its heart is a 1.5-liter turbocharged inline-four cylinder gasoline engine (code 15FNE) producing 155 horsepower. This engine functions solely as a generator, charging the 66 kWh lithium-nickel-manganese-cobalt-oxide (Li-NMC) battery pack positioned under the vehicle floor. A 313-horsepower electric motor (TZ210XS1141) drives the rear wheels. This design eliminates a mechanical link between the engine and the wheels, enabling efficient operation in both electric and hybrid modes. The engine incorporates direct fuel injection and a double overhead camshaft (DOHC) valvetrain for optimized combustion. The single-speed automatic transmission is tailored for the electric motor, delivering smooth and seamless power delivery. The 800V battery architecture facilitates faster charging times compared to lower-voltage systems.
Driving Characteristics
The LS6 II 1.5T delivers a refined driving experience. In all-electric mode, the vehicle offers near-silent operation and instant torque, resulting in brisk acceleration. The 0-60 mph time of 6.1 seconds is competitive within its class. When the battery is depleted or requires assistance during demanding driving, the gasoline engine seamlessly engages to provide additional power. The single-speed transmission ensures smooth transitions between electric and hybrid modes. While not as dynamically focused as some performance-oriented SUVs, the LS6 II prioritizes comfort and efficiency. The rear-wheel drive configuration contributes to balanced handling, though it may not offer the same all-weather capability as an all-wheel drive system.
Equipment & Trim Levels
The LS6 II 1.5T Extended Range comes standard with a comprehensive array of features, including a large touchscreen infotainment system, advanced driver-assistance systems (ADAS) such as adaptive cruise control and lane-keeping assist, and premium interior materials. Standard upholstery is typically a high-quality synthetic leather, with optional upgrades to genuine leather available. Optional extras include a panoramic sunroof, upgraded audio system, and air suspension for enhanced ride comfort. The dashboard layout is modern and minimalist, emphasizing the vehicle’s technological capabilities.
Chassis & Braking
The LS6 II employs a double wishbone suspension setup at the front and an independent multi-link suspension at the rear, providing a comfortable and controlled ride. Optional air suspension further enhances ride quality and allows for adjustable ride height. Ventilated disc brakes are used on all four wheels, providing ample stopping power. An anti-lock braking system (ABS) is standard, along with other safety features like electronic stability control. The vehicle also features 4-wheel steering (4WS) which improves maneuverability at low speeds and stability at high speeds.
Market Reception & Comparison
The IM LS6 II 1.5T has been generally well-received by automotive critics, who commend its long electric range, comfortable ride, and spacious interior. Compared to other PHEV SUVs in its segment, the LS6 II offers a competitive combination of performance, efficiency, and features. Its fuel economy of 0.06-5.32 l/100 km is impressive, and its all-electric range of 360-450 km is sufficient for most daily commutes. Some reviewers have noted that the interior design, while modern, may not appeal to all tastes.
Legacy
As a relatively new model, the long-term reliability of the IM LS6 II 1.5T powertrain remains to be fully established. However, IM’s commitment to quality and its utilization of proven battery technology suggest that this powertrain should prove durable and reliable. In the used car market, the LS6 II is anticipated to retain its value well, particularly among buyers seeking a stylish and efficient PHEV SUV. The vehicle’s advanced technology and extended electric range will likely make it a desirable option for years to come.
